Populasi Kumbang Elaeidobius kamerunicus Sebagai Penyerbuk Kelapa Sawit (Elaeis guineensis Jacq) Umur Dua Belas Tahun

Abstract

Weevil E. kamerunicus is the most efficient pollinator of oil palm. Pollination of E. kamerunicus replaced assisted pollination to natural pollination for increase fruit set. This study were aims to determine the population of E. kamerunicus in oil palm (E. guineensis Jacq) of 12 years after planting. Environmental factors which influence the population were studied. Observation of population of E. kamerunicus were done by sampling the weevil population in spikelet of male flower bunches in December 2009, February, and March 2010. Data population were showed in graphic, scatter plot, and analyzed based on Pearson correlation and its probability using Sigma Plot 11.0. E. kamerunicus populations was high in February 2010 and a low in March 2010. Weevil populations was high in the morning and low in the afternoon and evening. The number of spikelet per bunch affected the weevil population
